Specifications
- 380x TDK Invensense T3902 PDM microphones.
- Artix-7 A100T FPGA.
- FT601Q parralel-to-usb bridge tested at up to 200MB/s.
- 32x 40khz Ultrasonic Piezoelectric emitters
- 2 free GPIOs
Capabilities
Active sonar
- Optimized for 40KHz operation.
- Up to 5°x5° beamwidth.
- Range up to 8 meters depending on target sonar cross-section.
Passive sonar
- Can detect a bike air chamber leak at 3 meters.
Software
The sonar comes with two demoes - 2D Slicing camera, that shows the energyscape for a specific distance. - 3D Camera, that shows the reflected energy with a 3d point cloud.
Both examples are made with C99 C, using Raylib and Sokol for real-time 2D/3D visualization.
Attribution
The receiver hardware is based on the open-source CP SoM One

Questions
How big is the Lesonar2 beamforming rx hardware PCB?
It measures 144.7 × 92.3 mm and has 6 copper layers, 1.56 mm thick.
What parts does the Lesonar2 beamforming rx hardware use?
922 parts, built around the SN74AUP2G34DCKR(UMW), FT601Q-B-T, MMICT3902-00-012 and GSB343133HR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lesonar2 beamforming rx hardware KiCad files?
From the tornyol/lesonar2 repository on GitHub, at the commit this page was made from: the board is lesonar2_beamforming_rx_hardware/lesonar2_beamforming_rx_hardware.kicad_pcb and its schematic lesonar2_beamforming_rx_hardware/FPGA_bank0_vss.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lesonar2 beamforming rx hardware design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
